UNITED STATES To all whom it, may concern: h ,Be-it known'that 1, WILLIAM I L PEA RCE, a citizen-of the United States, residing at Chicago, in the county of Cook and Stateof Illinois, have inventedcertain new and use ful Improvements in Heat-Distributing Systems, of which the following is a specificationaqq. This invention relates to improvements in heat "distributing systems for distributing a heating medium in the form 'of steam, hot

ventionto provide an improved joint or. fit- 'ting for connecting the approxlmate ends of adjacent pipe sections which will prevent the escape of the heating medium while at the sa'me time the pipe sections will readily adjust themselves by the expansion and contraction of the sections of the main.

" A further object is to provide an improved anchor or support for the joint or fitting, the ends of which surround the joint or fit ting in such a manner as -to support the parts in true alinementnno matter in what position the joint-or fitting may be placed, and at the same time will overcome or prevent lateral displacement of the parts.

A further'obj ect is to provide an improved anchor or support for 'the joint so constructedthat access maybe readily had to the fastening screws or devices for operating the same to' adj-ust the packing gland.

To the attainment-of these ends and the accomplishment of other new and useful ohjects, as will appear, the invention consists in thefeatures of novelty in the "construction, combination andfarrangement ofthe *several parts hereinafter more fully" de- 5 scribed'and'claimed,'and'shown in the accompa-nying drawing illustrating an embodimentof the invention, and in which- Figure l-is a side view partly" in elevation and "partly in sectiom'showing an I j I s eiiiea'utabusti r;Pate t. j;

joint or fitting of this character constructed in accordancev with the principles of this invention. Fig. 2 is a sectional view on line 22"of- Fig. 1; Fig. 3 is a sectional View online 3-3 of Fig. 1. Fig 'd i s'a-n enlarged detail sectional View of'a' portion of the oint showing the packing.

Referring more particularly to the draw ing, and in the present exemplificati'on of,

the invention, the numeral l0"designates a support comprising a base which is"pro-" vided with supporting stands 11 spaced from each other and upon which the joint or fit.-

ting rests. The joint or fitting comprises a sleeve 12 which is preferably enlarged at its center, as at 13, to form a chamberwith, which, the openings through the ends of the may also be provided with an opening 14 which com-If amber 13 for the pur-- pose of securing a branch connection tothe' sleeve. As the-construction of each end=of sleeve communicate. The sleeve municates with the c the sleeveis the same, the specific description of one end will apply equally as well to the other. Arranged within the sleeve and spaced from the extremity of the end of the opening is a circumferential flange 15 which" forms a shoulder, and apipe section, 16 ex tends into the open end of the sleeve so that its extremity 17 will project through and beyond the flange 15. The diameter of the pipesection 16 is somewhat less thz'urthe diameter of the opening formedxby the flange 15, so that when the pipesect-ion-is secured in position, aspace 18 will be formed} between the flange and the periphery of the.-

pipe. Apacking gland 19 is also 'provided. a 'which surrounds the pipe secti-on,'- and jis spaced therefro-mto form a space 20'. :This? jpacki-ng gland-is supported and secured fin position by means of fasteningdevices'f 21 preferably in the'form of adjusting screws.

which on the, gland and a cooperating flange 23 on the'en'd of the sleeve; vThe packing gland I pass through a flanged portion; 22 i extends into the space between the sleeve and a the pipe section in advance of the flange 15 in thensual manner, and packingmaterial 24 is d'isposedbetween the pipe sectionland the sleeve and within the space formed be tween the end of the packing gland l9, and

p 'm imate wall :or face of the flange.

15, so that when the ju'sted infthe usual manner, the 'p'ac fluid-tight joint between the lpi packing gland I so that when the packing gland 19 is adjusted, the packing material 24 will be comfastening devices 28 are provided for securpressed and the rings or encircling members 25 will prevent thepacking material from entering the spaces while at the same time the pipe section will be held out of engagement with the faces of the flange and the packing gland.

Portions 26 of the periphery of the sleeve 12 adjacent each end are constructed on true circles, and the faces of the stands or supports 11 are also constructed on true circles to coincide with the portions 26. The sleeve is anchoredto the support, preferably by means of straps 27, which extend over the sleeve and rest upon the portions 26, and

ing the straps in position. These fastening devices are preferably in the 'form of headed bolts, one extremity of which passes through suitable apertures in the extremities of the straps 27 and are held from disengagement therewith by means of nuts or collars 29. The headed ends 30 of the fastening devices are'adapted to pass under shoulders 31 for-med preferably on the supporting stands or seats 11 and the outer faces of these supports or seats are provided with grooves 32 through which a portion of the fastening device 29 extends. The straps 27 may be adjusted by the nuts .or collars 29 so as to grip the sleeve, and when the nuts or collars are so adjusted, the heads 30 of the fastening devices will be drawn tightly against the shoulders 31 and the sleeve will be'securely anchored.

The pipe section 16 is provided at its free end with a radial peripheralflange 33, and loosely surrounding said extremity is a collar 34 which closely fits the pipe section, and this collar is provided with a recessed portion 35 in its outer face adapted to receive the flange 33. Another pipe section 36 is provided with a flange 37 adapted to cooperate with collar. 34, which latter also forms a ,flange, and arranged between these two flanges 37, 3st, is a packing gland 38. Suitable f stening devices 39 in the form of bolts are provided which pass through these flanges 37, 34 for securing the pipe sections togethenand for holding the packing gland vent the steam or fluid from leaking through the joint formed between the flange 33 and the collar or supplemental flange The support 10 is provided at each extremity with an annular portion 40 spaced some distance from the support or stand 11, and also from the adjacent extremity of the sleeve 12, and the packing gland 19. This annular portion 40 is preferably of some width and surrounds the pipe sections beyond the sleeve, and is so located that the supplemental flange formed by the collar 34; and the flange 37 will be encircled thereby. The inner face of this annular portion 40 contacts with the periphery of the collar 34 and the flange 39, and forms a bearing therefor within which the latter parts freely move during the longitudinal adjustment of the ipe sections and thereby forms a support to hold the pipe sections in true longitudinal adjustment with respect to the sleeve,

while at the same time it will prevent lateral displacement or a-djustmentof the pipe sections. This annular portion 40 also serves to support the pipe section 16 out of engagement with the sleeve 12, and also out of engagement with the flange 15, and the packing gland 19. By thus supporting the pipe section 16 so that it will not contact with the sleeve or the flange or packing gland, it will be apparent that the deposit or formation of foreign substances on the adjacent faces of theparts will not interfere with the proper longitudinal adjustment, while at the same time the arrangement of the packing herein shown will prevent the-escape of the heating fluid between the joints. It will also be apparent that by supporting the sleeve 12 at points remote from the extremities thereof, and by spacing the encircling portion 40 of the base 10 some distance from the sleeve, ready access may be had to the adjusting devices 21 without dismembering or interfering with the other parts. It will also be apparent that by the provision of the encircling members 10 and the anchoring straps 27, the joint or coupling may be supported at any angle and at the same time the parts will be held in true alinement.
